Abstract
An object of the present invention is to provide a production method with respect to spray pyrolysis, wherein regardless of the metal species the method readily yields a metal powder that has a uniform and homogeneous glassy thin film over the entire surface without local deposition of the glassy thin film on a specific portion of the metal powder surface. The method according to the present invention for producing a metal powder is a method for producing a metal powder provided on the surface thereof with a glassy thin film, wherein a glassy substance is produced in the vicinity of the surface of the metal powder by spray pyrolysis from a solution that contains a thermally decomposable metal compound and a glass precursor that produces a glassy substance that does not form a solid solution with the metal produced from the metal compound by thermal decomposition, so as to form the metal powder provided on the surface thereof with the glassy thin film. The glass precursor is prepared such that the melting temperature TmM of the metal and the liquid phase temperature TmG of the mixed oxide of the glassy substance satisfy the following formula (1): -100 [?C] ? (TmM - TmG) ? 500 [?C] (1).
